You are working with a patient in the ER room that is in severe pain from getting hit by someone in an automobile that did not pay attention to the patient crossing the street in the designated cross walk. They need a morphine-sulfate 0.9% NaCl I.V. dialysis bag to reduce pain. If the bag is composed of 1000mL of water, how many milligrams (mg) of NaCl are in this bag that the patient needs?
